DETAILED DESCRIPTION OF THE EMBODIMENTS

The following description is of the best-contemplated mode of carrying out the invention. This description is made for the purpose of illustration of the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.

Moreover, the terms “include”, “contain”, and any variation thereof are intended to cover a non-exclusive inclusion. Therefore, a process, method, object, or device that includes a series of elements not only includes these elements, but also includes other elements not specified expressly, or may include inherent elements of the process, method, object, or device.

FIG. 1 shows a schematic diagram of the management server according to a first exemplary embodiment of the disclosure. The management server 100 includes a plurality of storage units 110_1 to 110_N, a plurality of sub-servers 120_1 to 120_N and a load balancing unit 130.

Each of the storage units 110_1 to 110_N stores a datum, and N is a positive integer greater than 1. The storage units 110_1 to 110_N may be, for example, a form for storing data, such as cache with entity or block of a database without entity.

The database is used to store all the data of the management server 100 and unify all the data stored in the storage units 110_1 to 110_N. When a new datum is written in or updated, the database may distribute the datum to each of the storage units 110_1 to 110_N. In the embodiment, the datum stored in each of the storage units 110_1 to 110_N may be, for example, a portion of all the data stored in the database. That is, all the data stored in the database may be synchronized and uniformly distributed to each of the storage units 110_1 to 110_N. For example, if the quantity of the storage units 110_1 to 110_N is ten, the data quantity stored in the each of the storage units 110_1 to 110_10 respectively is the 1/10 data quantity of the database, or all the data of the database may be divided into ten blocks to store in the corresponding storage unit. The other embodiments are similar to the previous ones, and the description may be referred to the previous embodiment. The datum stored in each of the storage units 110_1 to 110_N may also been updated to be all the same, part of the same, or all different according to the using requirement.

Each of the sub-servers 1201 to 120_N respectively corresponds to the storage units 10_1˜110_N and obtains the datum from the storage units according to a request signal. In the embodiment, each of the sub-servers 120_1 to 120_N may be, for example, an entity or a virtual server device. Wherein, owing to the each of the sub-servers 120_1 to 120_N is respectively corresponds to the each of the storage units 110_1 to 110_N, the sub-servers may obtains the datum from the storage units one by one.

For example, the sub-server 120_1 corresponds to the storage unit 110_1, and the sub-server 120_1 may obtain the datum requested from the storage unit 110_1 according to the corresponding request signal. The sub-server 120_2 corresponds to the storage unit 110_2, and the sub-server 120_2 may obtain the datum requested from the storage unit 110_2 according the corresponding request signal. The other embodiments are similar to the previous ones, and the description may be referred to the previous embodiment. In FIG. 1, the sub-servers 120_1 to 120_N are separated from the storage units 110_1 to 110_N, and it is not limited to the disclosure. The storage units 110_1 to 110_N may also be built-in the sub-servers 120_1 to 120_N.

Additionally, the sub-servers 120_1 to 120_N may connect to the database periodically or non-periodically so as to update the datum stored in the storage units 110_1˜110_N at any time. Or, when a new data is added, deleted or updated in the database, the sub-servers 120_1 to 120_N may connect to the database immediately so as to update the datum stored in the storage units 110_1˜110_N at any time.

The load balancing unit 130 is coupled to the sub-servers 120_1 to 120_N and receives the request signal from a client. The request signal is generated by the client, and the request signal may include a request number. The request number may be, for example, a unique identification (UID) which formed as MAC address or formed as random string by English words, numerals or symbols.

When the load balancing unit 130 receives the request signal, the load balancing unit 130 can also obtain the request number in the request signal and distributes the request signal to the corresponding sub-servers 120_1 to 120_N according to the request number.

In the embodiment, a manner for distributing the request number is that request number is analyzed by using a mathematics method such as functional operation, and the foremost number or the last number of the analyzed request number is used.

For example, it is assumed that the quantity of the sub-servers is ten, such as the sub-servers 120_1˜120_10. When the foremost number or the last number of the request number obtained by the load balancing unit 130 is “1”, the load balancing unit 130 may distribute the request signal corresponding to the request number “1” to the corresponding sub-server 120_1. When the foremost number or the last number of the request number obtained by the load balancing unit 130 is “2”, the load balancing unit 130 may distribute the request signal corresponding to the request number “2” to the corresponding sub-server 120_2.

The other embodiments that the foremost number or the last number of the request number obtained by the load balancing unit 130 is “3” to “9” are similar to the previous ones, and the description may be referred to the previous embodiment. When the foremost number or the last number of the request number obtained by the load balancing unit 130 is “0”, the load balancing unit 130 may distribute the request signal corresponding to the request number “0” to the corresponding sub-server 120_10.

Then, the sub-servers 120_1 to 120_N obtain the datum from the corresponding storage units 110_1 to 110_N according to the received request signal. Afterward, the management server 100 outputs the above-mentioned datum to the client according to the request signal, such that the client may obtain the datum requested.

Further, in one embodiment, after the sub-servers 120_1 to 120_N obtain the datum from the corresponding storage units 110_1 to 110_N, the sub-servers 120_1 to 120_N may feed the datum obtained from the storage units 110_1 to 110_N back to the load balancing unit 130, such that the management server 100 outputs the above-mentioned datum to the client through the load balancing unit 130.

In another embodiment, the sub-servers 120_1 to 120_N may directly output the datum obtained from the storage units 110_1 to 110_N to the client. That is, the management server 100 may output the above-mentioned datum to the client through the sub-servers 120_1 to 120_N, so as to increase the speed for sending the datum back.

According to the above-mentioned description, the load balancing unit 130 distributes the request signal to the corresponding sub-servers 120_1 to 120_N and then the sub-servers 120_1 to 120_N only need to obtain the datum from the corresponding storage units 110_1 to 110_N. Additionally, the datum stored in the storage units may be classified and stored in advance, such that after the sub-servers 120_1 to 120_N receive the request signal, sub-servers 120_1 to 120_N may obtain the datum from the corresponding storage units 110_1 to 110_N quickly. Therefore, the time for searching the datum may be decrease effectively.

Further, When the sub-servers 120_1 to 120_N receive the request signal, the sub-servers 120_1 to 120_N may capture a predetermined request number stored in the storage units 110_1 to 110_N, and then compare the request number of the request signal with the predetermined request number, so as to determine whether the request signal received by the sub-servers 120_1 to 120_N is legal.

When the request number is equal to the predetermined request number, it means that the request signal is legal, the sub-servers 120_1˜120_N perform the corresponding process according to the request signal, i.e. the sub-servers 120_1 to 120_N obtain the datum from the storage units 110_1 to 110_N. If the request number is not equal to the predetermined request number, it means that the request signal is illegal, and then the sub-servers 120_1 to 120_N do not perform the corresponding process. Afterward, the sub-servers 120_1 to 120_N may wait for the next request signal distributed by the load balancing unit 130 and then perform the following process. Therefore, an efficiency decrease of the management server 100 related to an illegal request signal can be avoided.

In the embodiment of FIG. 1, the quantity of the sub-servers 1201 to 120_N and the storage units 110_1 to 110_N is greater than one, and it is not limited to the disclosure.

The request signal may also has, for example, two or more than two request numbers at the same time. The quantity of the request number may correspond to the quantity of the predetermined request number. For example, when the quantity of the request number is two, the quantity of the predetermined request number is two. When the quantity of the request number is three, the quantity of the predetermined request number is three. The other embodiments are similar to the previous ones, and the description may be referred to the previous embodiment. The embodiments of the request signals including two or more than two request numbers at the same time may be referred to the description of the above-mentioned embodiment, and the description is omitted.

Additionally, in the above-mentioned embodiment, the request number is analyzed by using the functional operation to distribute the request signal, and it is not limited to the disclosure. The request number may be analyzed by using the other manners similar to the functional operation to distribute the request signal, and the other manners for analyzing the request number are within the scope of the disclosure.

In the step S206, a datum is obtained by the sub-server from a storage unit according to the request number, wherein the storage unit is corresponding to the sub-server. In the step S208, the datum is outputted according to the request number. In the embodiment, the datum stored in the storage unit is a portion of all data stored in a database of the management server and all data stored in the storages are different.

FIG. 3 shows a flowchart of the operation method of the management server according to a third exemplary embodiment of the disclosure. In the step S302, a request signal is generated from a client, wherein the request signal has a request number. In the step S304, the request signal is distributed to a sub-server according to the request number, wherein the storage unit is corresponding to the sub-server. In the step S306, the request number is compared with a predetermined request number, i.e. it is determined that whether the request number is equal to a predetermined request number.

When the request number is not equal to the predetermined request number, the process returns to the step S302, the request signal is received from the client to perform the following process. When the request number is equal to the predetermined request number, the process goes to the step S308, the datum is obtained by the sub-server from the storage unit according to the request number.
